Smith, Loudonville, Ohio, and Richard H. Jordan, Fort Myers, Fla., assignors to Sentinel Frechek Locks, Incorporated, a corporation of Illinois Filed Mar. 3, 1964, Ser. No. 348,947 18 Claims. (Cl. 19432) The invention relates in general to a coin operated lock and, more particularly, to a combined coin and key operated lock mechanism.

Many coin operated locks have been used for lockers, for example, to exact monetary payment for the use of the locker. Storage lockers have been used in transportation depots for example, wherein the locker is unlocked and a key is provided which cannot be removed from the lock when the locker door is unlocked. Upon inserting the proper denomination of coin in the lock, the key may be turned to extend the lock bolt into locked position to lock the locker door with valuables inside the locker.

The present coin operated lock has particular advantages for use in such coin operated locks for lockers but has many additional related uses.

One of the more diflicult problems was that storage lockers were often desired in locations such as department stores wherein it was desired to provide lockable storage space for customers but it was not desired to charge for the use of the storage lockers, since this would deter many people from using the lockers. In other cases, expensive lockers and locks were provided with the feature of returning the coin after use of the locker, thus giving free service except for use of the coin before the lock could be locked and the key removed, the coin thus becoming a deposit for safe return of the key. These expensive and complicated locks and lockers, however, made the entire combination so prohibitively expensive to the department store that they seldom felt justified in investing in these lockers.

Accordingly, an object of the invention is to provide a lock to overcome the above disadvantages.

Another object of the invention is to provide a simple and economically constructed and assembled lock to provide free use of the locker.

Another object of the invention is to provide a lock which will provide free operation yet which requires a coin for operation in addition to the key, the coin assuring safe return of the key and the coin not being returned to the user until the lock has again been unlocked.

Another object of the invention is to provide a simple coin and key operated lock with a minimum of parts.

Another object of the invention is to provide a coin and key operated lock in a small and compact lock case which is the same size as standard cases and with the same bolt center mounting holes as non-key manual handles and latches for lockers.

Another object of the invention is to provide a lock for a locker which lock is coin and key operated yet the fact of coin operation is concealed from the exterior of the door.

Another object of the invention is to provide a coin and key operated lock with the increased safety for the lock, locker and its contents by concealing the fact that it is a coin operated lock.

Other objects and a fuller understanding of the invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

FIGURE 1 is an elevational view of a lock embodying the invention with the lock case cover removed;

FIGURE 2 is a partial view similar to FIGURE 1 showing a coin inserted;

FIGURE 3 is an enlarged partial view of the latch lever;

FIGURE 4 is a partial view similar to FIGURE 1, showing the key turned to extend the lock bolt;

FIGURE 5 is a sectional view of the lock on line 5-5 of FIGURE 2;

FIGURE 6 is a sectional view similar, on line 6-6 of FIGURE 2;

FIGURE 8 is a sectional view on line 8-8 of FIG- URE 7;

FIGURE 9 is a rear view of the lock. barrel; and

FIGURE 10 is a partial rear view of the lock case.

The figures of the drawing show a coin operated lock 11 which is one form which the invention may take. This lock 11 is illustrated as a coin and key operated lock which may be used with a locker 12 having a door 13 and a door frame 14. For example, this may be a storage locker such as used in transportation terminals or more preferably, may be in department stores or park and recreation facilities where free checking service in the locker 12 is desired. To this end, the lock 11 has been shown as a coin return lock having a coin return receptacle 15.

The lock 11 includes a lock case 18 which may be mounted on the inside 19 of the door 13. The lock case 18 may be made of sheet metal and may have upper and lower mounting flanges 20 and 21 with mounting holes 22 to permit fastening the lock case to the door 13. This lock case may have the same size and same distance between centers of the mounting holes 22 as conventional cases for non-key, handle operated latch mechanisms. This makes the coin operated lock 11 readily replaceable with such latch mechanism, to obtain coin-lockable latches on existing storage lockers. A metal cover plate 23 mates with the case 18 in complementary notches to form a part of the complete lock case. This cover 23 is shown removed in FIGURES 1, 2 and 4 for clarity.

A lock bolt 26 is reciprocable in the case 18 from a retracted position shown in FIGURE 1 to an extended position shown in FIGURE 4. These may be considered first and second positions of the lock bolt 26. In the extended position of FIGURE 5 the lock bolt may extend into a locking aperture 27 in the door frame 14 or extend behind a ledge on the door frame to lock the locker 12. A barrel 28 has first and second legs 29 and 30 which straddle the lock bolt 26 and provide a guide for the movement of this lock bolt 26. The outer ends of the legs 29 and 30 extend into apertures 31 in the rear wall 32 of the lock case 18 to fix the barrel to the case 18. The barrel 28 is hollow and receives a key cylinder 33 which is rotatable within the barrel upon turning of a key 34. A spring 35 may be mounted in a recess 36 in the lock bolt 26 to urge same to the retracted position. A crank arm 37 is fixed on the rear of the key cylinder 33 and fits within an elongated slot 38 in the lock bolt 26. This crank arm 37 may be considered an eccentric or an arcuately movable arm connected to the key cylinder 33 and connected to reciprocate the lock bolt 26 between the extended and retracted positions. In this case, the key cylinder has about a degree counterclockwise movement to lock the door, that is, to move the lock bolt from retracted to extended positions.

Surfaces 40 and 41 are provided in the lock bolt 26 and define a first coin chute 42. A slotted aperture 43 is provided in the top wall 44 of the case 18 to provide a second coin receiving chute. In the retracted position of the lock bolt 26, the first and second coin chutes are 3 in alignment which is a vertical alignment as the lock 11 is mounted in its usual position on the vertical inside surface 19 of the door 13.

A latch lever 46 is pivoted on a pivot pin 47 carried in the lock bolt 26. This latch lever 46 has first and second portions or ends 48 and 49, respectively. The second end 49 is longer than the first end 48 and, hence, heavier so that gravity causes the second end 49 to be urged downwardly normally into an engagement position as shown in FIGURE 1. The first end 48 extends into the coin chute 42 for engagement by the lower edge and one face of a coin 50. The second end 49 in the engagement position shown in FIGURE 1 is positioned for engagement with a first abutment 51 on the barrel 28 upon attempted extension of the lock bolt 26. This would be with the key and key cylinder 34 turned through a first small arcuate path. This causes the lock bolt 26 to move outwardly and causes the second end 49 of the latch lever 46 to strike the first abutment 51. This prevents extension of the lock bolt and locking of the locker 12.

The lock case 18 has a bottom wall 54 and an aperture 55 therein near one side wall. This aperture 55 may be considered a coin return aperture. The coin return receptacle 15 may be formed from metal of the case 18 and is connected to the bottom of the case 18 to receive a coin falling through the coin return aperture 55. The coin return aperture 55 is aligned with the second coin chute 43 and also aligned with the first coin chute 42 when the lock bolt 26 is in the retracted position. A second abutment 57 is provided on the cover plate 23 and is in vertical alignment below the second coin chute 43. This second abutment 57 has a forward edge 58. The barrel 28 has a second abutment 59 for possible engagement by the latch lever 46.

OPERATION The coin receiving chute 43 will not admit coins of a denomination larger than that for which the lock is designed to operate. If coins smaller than the proper coin are deposited, such coins or slugs will not be caught on the second abutment 57 and, hence, will fall all the way through the first coin chute and out into the coin return receptacle, 15. Thus, such smaller coins or slugs will not be capable of operating the lock 11. A coin of the proper denomination, when deposited in the coin receiving chute 43, will fall into the first coin chute 42 and will be retained therein by engaging the second abutment 57.

If no coin is present in the first coin chute 42, then the key 34 may be turned only through a first small arcuate path. This partially moves the lock bolt 26 until the second end 49 of the latch lever 46 engages the first abut- .ment 51 on the barrel 28. This is an abutment fixed relative to the case 18 and, hence, is an abutment acting between the lock bolt 26 and the case 18. This prevents further extensile movement of the lock bolt 26 and, hence, the locker 12 cannot be locked.

With a coin of proper denomination in the first coin chute 42, and as retained by the second abutment 57, the weight of this coin acts on the lever first end 48 to pivotally move this lever from the engagement position to a released position. This is as shown in FIGURE 2. The second end 49 of the lever 46 is moved upwardly so that it is not in a position to engage the abutment 51 or 59. Accordingly, the key cylinder 33 may be rotated by the key 34 a full 165 degrees in this case, which means that the key 34 is moved through first and second consecutive arcuate paths. The movement in the second arcuate path causes the crank arm 37 to move the lock bolt 26 to the completely extended position as shown in FIGURE 4. During this extensile movement of the lock bolt 26, the latch lever 46 moves with it in a generally longitudinal direction. In the extended position, the latch lever second end 49 may abut or come close to abutting the second abutment 59. This extensile movement also laterally moves the coin 50 and the first coin chute 42. The coin 50 is moved forwardly until it clears the forward falls by gravity partially out of the first coin chute 42 and rests on the bottom wall 54 of the lock case 18, but is still retained upright within the first coin chute 42.

In the extended position of the lock bolt 26, shown in FIGURE 4, the key 34 is removable from the key cylinder 33. This is permitted by the internal construction of the key cylinder 33 and its interaction with the key 34. Accordingly, a person who has checked his valuables inside the locker 12 and then deposited the proper coin, may lock the locker by counterclockwise key rotation and then remove the key to take the key with him. The coin remains in the coin operated lock 11 as a deposit as insurance for safe return of the key 34. Upon the persons return to the locker 12, the key 34 may be inserted in the key cylinder. Upon opposite rotation of the key 34, in this case through a degree clockwise are, the crank arm 37 cooperates with the elongated slot 38 to cause complete retraction of the lock bolt 26. Accordingly, the locker door 13 may then be opened sothat the person may recover his possessions. During this retractile movement of the lock bolt 26, the coin 50 is carried laterally in a rearward direction and when the lock bolt 26 is completely retracted, the first coin chute 42 will be in alignment with the coin return aperture 55 and the coin 50 will fall into the coin return receptacle 15. The lock 11 is again in the position shown in FIGURE 1 ready for another person to use the locker 12 and the key 34 is again captive in the key cylinder 33. A ledge 61 on the rear of barrel 28, see FIGURE 9, prevents full degree movement of the key cylinder 33, and this assures that the key remains captive in the retracted position of the lock bolt.

The coin return receptacle 15 may be changed to a coin retaining receptacle as a part of or connected to the bottom of the case 18 in case free service is not desired. In this case, the coins would merely fall into a retension receptacle which could be unlocked by a sepaarte lock mechanism and the coins removed periodically by a collection man.

The second abutment 59 prevents improper operation of the lock 11. If a person were to not use a coin and instead were to use a thin piece of metal such as a knife blade through the coin chutes 42 and 43 to depress the lever first end 48, then the key 34 could be turned and the lock bolt 26 partially extended. However, this beginning of extensile movement of the lock bolt 26 would cause misalignment of the first and second coin chutes 42 and 43 and the knife blade would have to be withdrawn before the lock bolt had moved very far. Accordingly, whereas the lever second end 49 might be raised to pass over the first abutment 51, it would then in this case, strike the second abutment 59. This would prevent full extension of the lock bolt 26 and thus the key 34 could not be removed. Accordingly, operation of the lock.11 without use of a coin 50 is precluded. The spring 35 would urge the lock bolt 26 back to the retracted position so that it would not stay in the partially extended position and, thus, the locker 12 will remain unlocked for use by the general public and not be put out of commission. The spring also urges the lock bolt to the retracted position so the coin chutes 42 and 43 are aligned, thus establishing the lock mechanism 11 in a position ready to accept a coin.

The unlocking of the locker 12 by retraction of the lock bolt 26 moves the coin 50 into the coin return receptacle 15. The person recovering his possessions will hear the coin fall into the coin return receptacle 15 and thus, as he opens the door 13 he will be reminded to reach into the coin return receptacle 15 to reclaim his coin as he recovers his possessions.

The latch lever 46 is a latch means having engagement and released positions and it has first and second portions. The first portion 48 is adapted to be disposed in the first coin chute 42 for engagement with a coin 50. This engagement invalidates the latch means or moves the latch to the released position at least upon movement of the key 34 through the first arcuate path. This permits the key to be moved through the second consecutive arcuate path to move the lock bolt from the first to the second position. In this embodiment shown, this is move ment from the retracted to the extended position, however, the lock might be made in the opposite manner for a coin unlocking lock. Thus, the presence of a coin would permit movement of the lock bolt from the extended to the retracted position. This could be effected merely by hav ing the lock bolt 26 move out of the opposite side of the case 18. The latch means 46 moves relative to the case 18 for movement between the engagement and released positions. The latch lever 46 may be considered a movable abutment arm having an end disposed in the first coin chute with this movable abutment arm cooperating with a latch shoulder 51 in the engagement position. The extensile movement of the lock bolt 26 establishes a condition where the coin 50 is moved downwardly within the first coin chute 42 yet is partially retained within this first coin chute 42. It is retained within the coin chute 42 until the lock bolt is moved back to the retracted position whereupon the coin is caused to move downwardly into the coin return receptacle 15.

It will be noted that the entire lock 11 is of very simple construction with few parts, easily manufactured and assembled. The lock case 18 has the key cylinder 33 symmetrically disposed relative to the mounting holes 22 and the entire lock case 18 is small and compact and may be of the same dimensions as the latch mechanism case of non-key handle-operated latch mechanisms. This permits the lock 11 to be substituted for such non-locking latch mechanisms on existing lockers. This provides coin and key operated lockers for free service of checking parcels and other possessions in existing lockers.

The lock 11 from the exterior of the locker 12 gives no indication or visible evidence that it is a coin operated lock. Only the key 34 is visible. It is not until one opens the locker door 13 that one may read the simple instructions showing that the parcels should be placed in the locker, then a coin inserted in the coin chute 43 and the door closed, The key may then be rotated to lock the locker and the key removed. This lack of visible evidence that the locker is coin operated is a great deterrent to vandalism. It has been found that the mere indication that lockers are coin operated indicates two things to vandals. One, that the lockers contain money in the locks and the lockers must contain valuable items in order to require coin operated locks. This is a double invitation to vandals to destroy the locks and lockers to attempt to recover the money and Valuable contents in the lockers. In this case, however, the lock is mounted on the inside of the door 13 rather than being visibly mounted in the door frame 14 as in many prior forms of coin and key operated lockers. Thus, the lock mechanism is not exposed in a place inviting pry-out techniques of breaking into the lock or locker. Further, no handle is required on the locker 12 since the key in the unoccupied locker serves as a handle for opening the door. Thus, one additional item is saved in the cost of manufacture and one additional item is eliminated which is a place for vandals to attempt to gain access to the lock or locker.
